|---|---|---|---|---|
| On Geometric Strain Limit | If set to Yes, elements will automatically erode if the geometric
strain in the element exceeds the specified limit. This field is not available for LS-DYNA. | Yes | Yes | |
| Geometric Strain Limit | The geometric strain limit for erosion. Recommended values are in the range from 0.75
to 3.0. The default value is 1.5. This field is not available for LS-DYNA. | Yes | Yes | |
| On Material Failure | If set to Yes, elements will automatically erode if a material
failure property is defined in the material used in the elements, and the failure criteria
has been reached. Elements with materials including a damage model will also erode if damage
reaches a value of 1.0. This field is not available for LS-DYNA. | Yes | Yes | |
| On Minimum Element Time Step | If set to Yes, elements will automatically erode if their calculated time step falls below the specified value. | Yes | Yes | |
| Minimum Element Time Step |
The minimum controlling time step that an element can have. If the element time step drops below the specified value, the element will be eroded. | Yes | Yes | |
| Retain Inertia of Eroded Material |
If all elements that are connected to a node in the mesh erode, the inertia of the resulting free node can be retained if this option is set to Yes. The mass and momentum of the free node is retained and can be involved in subsequent impact events to transfer momentum in the system. If set to No, all free nodes will be automatically removed from the analysis. | Yes | No |
